Systolic blood pressure is a measure of the force your heart exerts on the walls of your arteries each time it beats. In adults, systolic blood pressure measurements follow a normal distribution with a mean value of 116.91 mmHg (millimeters of mercury) and a standard deviation of 6.354 mmHg. Please use this information to answer the following question. a. Suppose an adult's systolic blood pressure is considered to be "low" if it is below 102 mmHg. What is the probability that a given adult will have low systolic blood pressure? Answer: (Round to at least FOUR digits after the decimal if necessary.)
